As the world's most popular MOBA, League of Legends runs on a proprietary engine that has been updated for over a decade. Recently, Riot increased the minimum requirements to include AVX instruction support and dropped support for older OSs and DirectX 9. While still lightweight, modern team fights with complex particle effects can strain older integrated graphics. The game scales well with single-thread CPU performance, meaning even modern entry-level processors can deliver high frame rates.
Actual FPS may vary based on RAM speed, background processes, and other system factors

At 1080p low, the Ryzen 3 PRO 4350G sets the ceiling at about 274 FPS, while the GeForce RTX 4090 could reach 700 FPS. In this scenario, the CPU limits the GPU potential by 61% (FPS gap: 426 FPS). Overall distribution: CPU limits 12/12 cells, GPU limits 0/12, balanced 0/12.
Your Ryzen 3 PRO 4350G is the limiting side in the heaviest mismatch. This means part of the GeForce RTX 4090 rendering potential remains unused in those settings.
| Resolution | Low | Medium | High | Ultra |
|---|---|---|---|---|
| 1080p (Full HD) | CPU Limits GPU 61% | CPU Limits GPU 53% | CPU Limits GPU 43% | CPU Limits GPU 34% |
| 1440p (2K QHD) | CPU Limits GPU 58% | CPU Limits GPU 48% | CPU Limits GPU 36% | CPU Limits GPU 21% |
| 4K (Ultra HD) | CPU Limits GPU 41% | CPU Limits GPU 31% | CPU Limits GPU 25% | CPU Limits GPU 22% |
We estimate the maximum FPS the processor can sustain and the maximum FPS the graphics card can sustain in each setting, then compare those limits directly.
Limit Factor formula: (stronger - weaker) / stronger. Example: if CPU ceiling is 200 FPS and GPU ceiling is 140 FPS, then GPU limits CPU by 30%.
CPU Limits GPU means the processor ceiling is lower. GPU Limits CPU means the graphics ceiling is lower. Balanced means the FPS ceilings are close enough that the gap is negligible.
The displayed percentages are derived from FPS ceilings, not generic utilization heuristics.

The Ryzen 3 PRO 4350G + GeForce RTX 4090 pairing runs this title with CPU utilization between 26% and 59% and GPU utilization between 44% and 80%. Ryzen 3 PRO 4350G keeps significant headroom across presets, while GeForce RTX 4090 is utilized efficiently without persistent saturation. As resolution scales, average GPU load rises from 46% at 1080p to 76% at 4K, while CPU averages move from 43% to 33%.
The utilization pattern is relatively balanced. The GeForce RTX 4090 reaches 78% average at its highest-load preset, while the Ryzen 3 PRO 4350G peaks at 46% average, with no single component consistently acting as a hard bottleneck.
At 1080p, averages sit around CPU 43% and GPU 46%. At 1440p, that shifts to CPU 33% and GPU 52%, and at 4K it reaches CPU 33% and GPU 76%. This shows that workload scaling is present on both components, with stronger pressure on the GPU.
4K (Ultra HD) Ultra is the most balanced preset based on this dataset. It runs around CPU 32% (29-36%) and GPU 78% (77-80%), which keeps GeForce RTX 4090 well utilized without constant max-out behavior while Ryzen 3 PRO 4350G remains stable for consistent frame delivery.
Current utilization does not show an urgent upgrade requirement for either component; the Ryzen 3 PRO 4350G and GeForce RTX 4090 remain reasonably matched for this title.

Yes, the Ryzen 3 PRO 4350G paired with the GeForce RTX 4090 can run League of Legends smoothly up to 4k achieving around 182 FPS at Ultra quality. Your GPU is 1277% above the recommended specs, and your CPU is 71% above the recommended requirements.
This CPU + GPU combo costs approximately $1754.5 ($105.5 CPU (Rank #175 Value) + $1649 GPU (Rank #77 Value)). Since the CPU is the main limiting factor, investing in a stronger processor will improve your framerates and overall value. For example, the Ryzen 9 9950X is a great upgrade option for around $649 (Rank #5 for value).
For League of Legends, upgrading the CPU would have the biggest impact on performance. The Ryzen 3 PRO 4350G is currently the limiting factor — the GeForce RTX 4090 has extra headroom that a faster processor could take advantage of. This is especially noticeable at 1080p where CPU performance matters more. CPU-limited at: 1080p low, 1080p medium, 1080p high, 1080p ultra, 1440p low, 1440p medium, 1440p high, 1440p ultra, 4k low, 4k medium, 4k high, 4k ultra.
League of Legends does not currently support Frame Generation technologies like DLSS 3 or FSR 3. Your performance is based entirely on native rendering. If the game adds support in a future update, newer GPUs will benefit the most.
League of Legends requires at minimum a Core i3-530 (CPU) and GeForce 9600 GT (GPU) with 2 GB RAM and 16 GB storage. For the recommended experience, you need a Core i5-3330 and GeForce GTX 560 with 4 GB RAM. Your Ryzen 3 PRO 4350G and GeForce RTX 4090 both exceed the recommended specs, so you're well-positioned for a great experience.
These League of Legends FPS results are not arbitrary numbers. They come from calculations informed by thousands of real gaming benchmarks, and the typical accuracy range is around 10% to 15%. That makes them far more useful than generic FPS calculators that simply invent values without a benchmark foundation. Actual in-game performance can still vary with drivers, updates, RAM configuration, cooling, and the exact scene being rendered.
Performance estimates are based on synthetic benchmarks and hardware capabilities.
Results may vary based on drivers, OS, and background processes.
